German EVG Lufttechnik valves, EVG Lufttechnik models, EVG Lufttechnik prices

EVG Lufttechnik valves, also known as self-acting balance valves, flow control valves, flow controllers, dynamic balance valves, and flow balance valves, are intuitive and simple flow regulation control devices. When applied in pipe networks, the flow control valve can set the flow rate directly according to the design. Under the action of water, the valve automatically eliminates flow deviations caused by residual head and pressure fluctuations in the pipeline. Regardless of how system pressure changes, the set flow rate remains constant. These functions allow the pipe network flow regulation to be completed in one step, turning network balancing into simple flow distribution, effectively solving hydraulic imbalance in the pipe network. Flow control valves are mainly applied in: central heating (cooling) and other water systems, enabling on-demand flow distribution in the pipe network, eliminating hydraulic imbalance in water systems, and solving uneven heating/cooling problems.

EVG Lufttechnik valve operating principle

By receiving signals from industrial automation control systems (such as: 4~20mA), it drives the valve to change the cross-sectional area between the valve core and valve seat, thereby controlling process parameters such as flow, temperature, and pressure of the pipeline medium. This achieves automated regulation functionality.

EVG Lufttechnik valve structure

Self-acting pressure regulating valves do not require external energy sources such as power or air supply; they rely solely on the energy of the medium itself for drive. They are energy-saving, environmentally friendly, and easy to use. After installation, simply set the pressure value to begin automatic operation. Therefore, they are increasingly widely used in applications where control precision requirements are not high and where power or air sources are lacking. However, during use, attention must be paid to the specificity of model selection, otherwise accidents may easily occur. During use, pay attention to model selection and installation environment; therefore, a detailed understanding of the working principle and structure of self-acting pressure regulating valves is very important.

EVG Lufttechnik valve applications

The self-operated pressure regulating valve (hereinafter referred to as the pressure valve) is an energy-saving product that automatically regulates pressure by relying solely on the pressure changes of the medium itself, without requiring external energy sources. It integrates measurement, actuation, and control functions. It is widely applicable in industrial sectors such as petroleum, chemical, metallurgy, and light industry, as well as in urban heating and space heating systems. This product can be used as a pressure control device for non-corrosive media, including liquids, gases, and steam, with a maximum temperature of 350 °C.
